Guys.
the 'OTHER" is obviously the downed pools hashing power. everybody is still mining with them, it is just the front end that wont answer http calls.
No everyone isn't mining.
Many users of deepbit report connectivity issues and none of my miners can connect to slush. It looks like some miners may still be able to connect but not all of them are.
Still other isn't necessarily bad. My slush rigs switched to solo so they would be "other" too.
